I am in need of the heater return hose for 1980 euro 635 with M90 motor. I've attached a picture since no US parts suppliers seem to know what I need.
It goes on the bottom of the heater core outlet and over to the rear of the head and attaches to a 90 degree fitting. It measures. 12" from outside to outside

Re: heater return hose
From what I just saw on realoem, they are still dealer available. I have an 81 euro with M90 and that is where I bought them.Looks like all 4 hoses are available

Re: heater return hose
I just went to realOEM, for the first time. thank you, and the number 1364770 is the input/top hose. If you happen to have the bottom or return hose number, I would appreciate it. My number is is not completely legible.

Re: heater return hose
The part numbers I see are 64211369934 for the inlet and 64211368715 for the return. Plug those into the space provided for realoem part search. I don't see any hoses with the part number you show unless I am missing something?? Also remember you have the early heater valve that looks like a large hocky puck

Re: heater return hose
without tearing into the interior to see my hockey puck, what I have are to approx. 5/8" tubes sticking out of the fire wall. One (top) appears to go towards left side plumbing and the bottom goes to back of head and attaches to a metal 90 degree bend. That is the hose shown at the beginning of my request.
Another thing that bothers me is that my car is listed as a M30 and it is definitely M90 motor with matching VIN's as seen on starter plate?

Re: heater return hose
All M90's show as M30. There is no special classification for them. All Euro 635s up to May of model year 1982 were M90's
